IMPROVEMENT IN MACHINES FOR THE MANUFACTURE 0F MOLDINGS.

The Schedule referred to In' these 'LettersiPatent and making part:v of the same.

To all whom it may concern Be it known that we, JOSEPH C. COOKE and HENRY A.WH1TELEY, in the town ot' Preston, in the county ot' New London and State oi' Connection, have in, vented a certain new and useful Improvement in Molding-Machines; and we do hereby declare that the following is a full, clear, and exact ldescription of the construction and operation of the same, reference 'being had to the accompau ying drawing making a part of this specification, in which"- Fjgure 1- is a plan view.

Figure 2, a side elevation.

Like letters in both figures ot' the drawing indicate like parts.

Our invention consists in the arrangement in a molding-machine of a rotaryrpolisher with the cutting,- tool of the same, the polisher beingxmade to correspond with the shape ofthe tool, and arranged beyond the same on the machine, so that the molding passing from the cutting-tool will be brought in contact with the-polisher, and thus made smooth and ready for use before leaving the machine; the object oi' the invention being to economize time in the smoothing of moldings.

We are also enabled by the .above arrangement to sharpen the cutting-tool on the polisher with greater convenience and accuracy than can be obtained by the ordinary and usual method of sharpening the same.

To enable others skilled in the art to make and use our invention, we will proceed to describe its' construction and operation.

A represents a molding-machine.

B, the arbor carrying the cutting-tool C. D, the'arbor carrying the p'olisher E, which latter consists of a circular block of iron or steel provided with a coating of emery, and arranged at a suitable Y distance beyond the cutting-tool O, and made to`conform in shape to that of the same. l

F is the bed of the machine, on which the material is placed to be molded.

H H are pulleys, connected by band, the motion of the pulley on the arbor of the cutting-tool 4being communicated to that ou the arbor of the polisher:

|lvhe molding passes along on the bed of the machine, and,after leaving the cutting-tool, passes under the polsher, whence it is made smooth and ready for use before leaving the machine.

The shape of the polisher being the same 4as that of the cutting-tool, it ofcourse follows that the former will it and polish the molding properly, and it will be readily seen, by removing the cutting-tool from its fastenings, it can be .sharpened on thepolisher with greater convenience and accuracy than as ordinarily.

'Having thus fully described our invention,

What we claim 'therein as new,` and desire to secure In a molding-machine, the arrangement of a rotary polisher beyond the cutting-tool of the same, substantially as and for the purpose set forth.
